The 75 mm Howitzer Motor Carriage M8 was a self-propelled howitzer vehicle of the United States developed during the Second World War.

Development[edit]

It was developed on the chassis of the then-new Light Tank M5 (Stuart VI). The prototype was designated the T17E1 HMC[1]. It had the standard M5 turret removed and replaced with an open-topped turret and the drivers' hatches moved from the hull roof to the glacis plate.

Armament[edit]

Armament consisted of a new open-topped turret armed with a 75 mm M2 howitzer, later a 75 mm M3 howitzer, which were reworks of the M1A1 pack howitzer. It carried 46 rounds of 75 mm ammunition; types of ammunition carried were Smoke M89 and H.E. (high explosive) M48. Unlike the standard M5 Light tank, the M8 featured no hull-mounted or coaxial Browning M1919A4 .30cal machine guns. A Browning M2HB .50cal machine gun with 400 rounds was mounted on the right rear corner of the turret for local defense and anti-aircraft purposes.

Production[edit]

The T17E1 HMC was ordered into production as the 75 mm Howitzer Motor Carriage M8 in April 1942. Production ran from September 1942 to January 1944. A total of 1,778 vehicles were produced by Cadillac Motor Car Co.

Combat service[edit]

The M8 was used in the Italian Campaign, the Western Front, and in the Pacific Theater of Operations by the US Army and on the Western Front by the French Army. It was also used by the French Union and State of Vietnam during the First Indochina War. It stayed in French service until the 1960's and saw service in Algeria.
